when do i do a water change? my levels are all perfect, but there are a few brown spots on the substrate. there are also a couple of brown spots on the live rock. do i clean the live rock? if so...how? and should i clean the substrate? i dont know where it was ( it might have been here ), but i read that your levels could be fine, but as soon as you stir the substrate your levels can go up.
thank you for your time :dance2:
